Ambiguity with ForwardDiff

[dlfivefifty]

Not sure where the right place to fix this is but we currently have:

ERROR: MethodError: *(::ForwardDiff.Dual{ForwardDiff.Tag{var"#15#16", Float64}, Float64, 2}, ::Infinities.Infinity) is ambiguous. Candidates:
  *(a::Real, y::Infinities.Infinity) in Infinities at /Users/sheehanolver/.julia/packages/Infinities/lXuMq/src/Infinities.jl:223
  *(x::ForwardDiff.Dual{Tx, V, N} where {V, N}, y::Real) where Tx in ForwardDiff at /Users/sheehanolver/.julia/packages/ForwardDiff/QOqCN/src/dual.jl:139
Possible fix, define
  *(::ForwardDiff.Dual{Tx, V, N} where {V, N}, ::Infinities.Infinity) where T

those methods should be in an extension
